US Patent 11169559 Pedal device for a vehicle

A pedal device for a vehicle includes a first link that is pivotally supported at one end and receives a pedaling force of a driver, a return spring that biases the first link toward a standard position, a second link supported so as to be pivotable in a direction opposite to that of the first link, and a third link transmitting force and displacement between the first and second links. The return spring has a first and second ends connected to the first and second links, respectively, A moment in which a tensile force of the return spring pivots the first link toward the standard position is greater than a moment in which the tensile force of the return spring pivots the first link away from the standard position via the first end.
